With nearly every technological application, periodic preventive maintenance reduces the need for repairs and extends the life of equipment. Specifically speaking, a very common problem associated with central air conditioning and commercial refrigeration units is clogged drainpipes. Not detected in time, a clogged pipe may overflow, causing extensive water damage to walls, wooden beams, and so on. The solution is not always easy or apparent, especially to many homeowners. A service call to a professional is one approach, but may come at a fairly steep price. The long-standing but heretofore unfulfilled need for an automated drain-cleaning system, without disrupting normal operation, is now met by a new, patented, easy-to-install, non-disruptive invention: the Green Vacuum™, the world’s first and only preventive, automated drain system. Eliminate costly repairs, potential health risks and unnecessary electrical expenses by taking advantage of the range of eco-friendly, cost-friendly benefits offered by the easy-to-install, hands-free the Green Vacuum™, the world’s first and only preventive, automated drain system. Remember that it’s always better to prevent than to regret!
